1. An instrument comprising:

  • a handle having a handle distal end and a handle proximal end;

    a handle end cap of the handle having a handle end cap distal end and a handle end cap proximal end;

    a handle base of the handle having a handle base distal end and a handle base proximal end;

    an actuation control mount of the handle having an actuation control mount distal end and an actuation control mount proximal end wherein the actuation control mount distal end is disposed in the handle base and wherein the actuation control mount proximal end is disposed in the handle end cap;

    an actuation control of the handle having an actuation control distal end, an actuation control proximal end, an actuation control anterior end, and an actuation control posterior end, the actuation control disposed within the actuation control mount wherein an application of a first force vector directed towards the handle distal end and away from the handle proximal end to the actuation control anterior end is configured to rotate the actuation control in a first direction and wherein an application of a second force vector directed towards the handle proximal end and away from the handle distal end to the actuation control anterior end is configured to rotate the actuation control in a second direction;

    an actuation chamber disposed in the actuation control, the actuation chamber extending completely from the actuation control distal end to the actuation control proximal end;

    a housing tube having a housing tube distal end and a housing tube proximal end, the housing tube having dimensions configured to perform microsurgical procedures; and

    an optic fiber having an optic fiber distal end and an optic fiber proximal end, the optic fiber disposed in the housing tube, an inner portion of the handle, and the actuation chamber wherein a geometry of the actuation chamber is configured to prevent a contact between a portion of the actuation control and a portion of the optic fiber due to a rotation of the actuation control and wherein the optic fiber distal end is adjacent to the housing tube distal end.
